TEXTURE AND MICROSTRUCTURE EVOLUTION DURING COLD ROLLING OF A STRIP CAST AND OF A HOT ROLLED AUSTENITIC STAINLESS STEEL

摘要

The microstructure and texture evolution of a strip cast and of a hot tolled austenitic stainless steel (18/100 Cr, 8.5/100 Ni) during cold rolling was studied (maximum thickness reduction △d/d_o = 80/100). The microstructure of the hot band was homogeneous through the sheet thickness, except that in the centre Layer a small volume fraction of martensite appeared. The hot band texture revealed a through-thickness Gradient which was discussed in terms of the shear distribution during hot tolling.
